MAMMALIA. 
ceros is an exceedingly sliy and timid animal, and Sir T. Stamford 
Raffles remarks of it : — “ They are not bold, and one of the 
largest size bas been seen to run away from a single wild dog.” 
( Cams rutilans, a peculiar species) . Dr. Cantor heard of it in the 
Malayan peninsula, as an inhabitant of Province Wellesley, fre- 
quenting only the densest and most inaccessible jungles. He 
also gives both R. indicus and JR. sondaicus as inhabiting the 
Malayan peninsula, but did not procure specimens or other indicice , 
and we doubt if he wrote on personal knowledge, or that he 
had actually seen and compared the skulls of both species. It 
may be added that C. sumatranus, like R. sondaicus is found at all 
elevations, but that the two do not usually inhabit the same 
districts. 
In the course of personal investigations in the province of 
British Burmah, the author of these addenda obtained the spoils 
of both the lesser One-horned and of the Asiatic Two-horned 
Rhinoceroses. Of the latter a full-grown male was staked within 
a distance of not more than five miles of him, in Upper Mor- 
tabon, but the intervening ground was impracticable, and he only 
succeeded in obtaining the facial portion of the skulls, with the 
two horns attached to the skin covering it. The small size of 
the bones seemed to indicate a young animal, but when, after 
maceration in water, the skin (with the horns attached to 
it) was separated from the bone, the complete anchylosis of 
the nasals proved that it was by no means immature. The 
thought occurred that the horns of a Rhinoceros, consisting 
merely of agglutinated hairs, might, under rare circumstances, be 
shed in a mass, and subsequently renewed, which was the only 
way that the small size of the horns upon this tolerably aged 
animal could be accounted for. We have since learned that a 
great One-horned Rhinoceros, at this time living in the Zoological 
Garden at Moscow, did actually shed a horn, which is now in the 
museum of that city, and that another has since grown in its 
place. So the rudimentary frontal horn of the old female of the 
same species now in the London Zoological Gardens was roughly 
broken off on one occasion, and the blood flowed very profusely ; 
but another hornlet has since been developed in its place, and 
there can now be no doubt that the same occasionally happens 
with wild animals.
